[Oviyam] Error after login Oviyam in Tomcat using Eclipse

[Suhaili Junaidi]

Hello. I am using Tomcatv7.0 and Oviyam 2.7.3. I've copied the jar files into the Tomcat lib folder. I managed to log in after editing tomcat-users.xml but I got these errors. I am running the oviyam.war file from EclipseEE 2022 (4.23.0) by the way. Please guide me.
